Problems solved by technology
[0006] The purpose of this disclosure is to provide a time-sharing wave recording method, so as to solve the problem that traditional power equipment needs to use a wave recording device independent of the control unit for wave recording, which leads to increased development and testing time and product costs for traditional power equipment, and in In the various stages of development testing and product troubleshooting, it is impossible to use the wave recording device for special analysis and processing.

The invention discloses a time-sharing wave recording method. The method comprises the following steps of: (a) selecting N1 operating variables from a plurality of defined operating variables, and mapping storage addresses of the N1 operating variables into N1 pointer variables; (b) providing N2 recording channels, and establishing a mapping relationship from the N1 pointer variables for each recording channel; (c) when a start trigger signal is received at a rising edge stage of any pulse of a working clock, endowing a first recording channel with the value of an operating variable corresponding to a mapped pointer variable, and when the start trigger signal exists, endowing values of the operation variables corresponding to the corresponding pointer variables to the remaining recording channels in sequence, storing the value endowed by each recording channel in a memory for wave recording, and ending wave recording when an embedded system receives an end trigger signal.
Description
technical field [0001] The present disclosure is a time-sharing wave recording method, in particular to a time-sharing wave recording method applied to an embedded system of a power supply device Background technique [0002] The embedded system is usually embedded in the control unit of the integrated power supply equipment, provides control signals to the electromechanical devices in the same equipment, and has general functions such as monitoring and communication at the same time. How to improve the safety, reliability and high performance of power supply equipment with embedded systems is the current direction of the industry's efforts. [0003] There may be faults or abnormalities in power supply equipment during operation. Therefore, in order to quickly diagnose and locate the source of the fault, some traditional power supply equipment uses an additional wave recording device to record the characteristics of the power supply equipment during operation. In this way, u...
